Most of the examples considered below have been presented in [1]}, [2]} where they are obtained from five-dimensional considerations. Our results, obtained in a purely four-dimensional way, can be matched exactly by taking the following dictionary between expansions into account:
\(\begin{split}&\left(\frac{1}{1-t^{-\alpha _i}}\right)^+\longleftrightarrow \left[\frac{1}{1-t^{-\alpha _i}}\right]^-,\\[.6em]&\left(\frac{1}{1-t^{-\alpha _i}}\right)^-\longleftrightarrow \left[\frac{1}{1-t^{-\alpha _i}}\right]^+,\end{split}\)
